06Cr17Ni12Mo2 Stainless Steel Coil & Plate | GB/T 4237 06Cr17Ni12Mo2（316) Stainless Steel Sheet Manufacturer & Exporter – Gangsteel

Gangsteel is a leading manufacturer and global exporter of GB/T 4237 06Cr17Ni12Mo2 stainless steel hot-rolled coils, plates, and wide heavy plates. Internationally recognized as Grade 316 — the second most widely used austenitic stainless steel after 304 —06Cr17Ni12Mo2 offers significantly superior resistance to pitting, crevice corrosion, and chloride-induced stress corrosion cracking thanks to its 2.0–3.0% molybdenum content. It is the benchmark material for applications involving chlorides, acids, marine environments, chemical processing, and food/pharmaceutical equipment where standard 304 would be insufficient.

With 16–18% Cr, 10–14% Ni, and 2–3% Mo, 316 delivers excellent general corrosion resistance in fresh water, seawater, dilute acids, and organic chemicals, combined with outstanding formability, weldability, and hygienic properties. Gangsteel supplies 06Cr17Ni12Mo2 under GB/T 4237-2015 (Stainless Steel Hot-Rolled Sheets and Strips) in thicknesses from 2 mm to 500 mm and widths up to 4200 mm — one of the widest hot-rolling capabilities available globally. Our products are delivered in standard hot-rolled finishes No.1 (annealed & pickled) and 2D (annealed & pickled dull) and are exported to over 60 countries for demanding industries including chemical, petrochemical, marine, food processing, pharmaceutical, desalination, and architectural applications.

FAQ

Q1: What is the main advantage of 316 (06Cr17Ni12Mo2) over 304?

A: 316 contains 2–3% molybdenum, providing significantly better resistance to pitting, crevice corrosion, and chlorides (PREN ~24–26 vs. ~19 for 304), making it suitable for marine, chemical, and acidic environments.

Q2: Can 06Cr17Ni12Mo2 be used in seawater or highly acidic conditions?

A: Yes, it performs well in many chloride and dilute acid applications, but for severe seawater or concentrated acids, duplex grades (2205/2507) or higher-Mo alloys may be preferred.

Q3: What finishes are available under GB/T 4237 for hot-rolled 316?

A: Standard finishes are No.1 (annealed & pickled) and 2D (annealed & pickled dull). No.1 is most common for further processing.

Q4: What is the maximum width and thickness Gangsteel can produce for 06Cr17Ni12Mo2?

A: Up to 4200 mm wide and 500 mm thick in hot-rolled plates; coils typically 2–25 mm thick.

Q5: Is 316 weldable? What filler should be used?

A: Yes, excellent weldability. Use ER316 or ER316L fillers to match the molybdenum content.

Q6: Does Gangsteel offer third-party inspection for GB/T 4237 316 material?

A: Yes — SGS, TUV, BV, or customer-nominated agencies are welcome at any stage.

Q7: What is the lead time for hot-rolled 06Cr17Ni12Mo2 coils or plates?

A: Standard sizes from stock: 7–15 days. Custom wide/heavy plates: 25–45 days depending on thickness and quantity.

Q8: Can Gangsteel provide 316 with BA or 2B finish?

A: Hot-rolled material is No.1 or 2D. For BA or 2B, we supply cold-rolled versions under GB/T 3280.
